The old novak system had thermaling issues. The GTB is built to handle the current of the 4.5 and 5.5 motors so i doubt that it will overheat with the ss4300. Unless you have it wildly overgeared. It should be a good class, probably a little faster than stock and zero motor maintenance.

I run the 4300 motor in a pan oval class. I've thermalled once. I've known others who have thermalled a couple times. I was wondering if the motor actually loses anything everytime it thermals.

I've heard someone say that after 6 thermals you should change the rotor, I don't know how true this is.

it shouldnt do any damage as the thermal shutdown is designed so that it stops the unit from overheating... so what would be the point of it shutting down but still doing damage?

every time that you thermal the rotor (magnet) will get weaker

Just keep an eye on your motor temp to prevent harm to your rotor. Per Charlie @ Novak, you do not want the motor to exceed the 160-165 deg F range after a run. When you thermal, the motor temp is in the 175 plus deg range.

Thats true

So by replacing the rotor, it should be back to its better or close to its optimum strength?

Hi All,

I am looking for a reasonably priced Novak SS ESC and 4300 motor.

I thought some of you guys may have upgraded to the GTB and have an older version you are no longer using.

At my track we have a 19t class. The 4300 is allowed - loses some on the long straight but makes up for it in the twisties.

Help !!

We tried combining them at our track. The 19Ts were much faster all the way around. About 1.5 seconds per lap on a ~14 second lap. And that was geared way high to the point of risking thermaling it.

the 5800 is about dead even with a real hot 19 turn.thats what we have been running at out local track.

I put the updated rotor and endbell in my 5800 and it made it have a TON of torque and less top end. In fact, the torque was so high my diffs couldn't handle it. The improved endbell works great in the 4300, but I'm not sold on it in the 5800 when racing with 19T.

And yea, the 4300 even at its best is firmly between stock and 19T. If you look at the results from last year's Novak race where they had a 4300 class full of factory drivers, you can verify this. Faster than stock, slower than 19T. In all honesty, it's a really nice compromise between the two.

I still think the 5800 is a bit faster than 19T, but it's pretty close.

Since the LRP Sphere was brought up... I would like to share my experience with it and LRP. One MAJOR & SERIOUS problem the original Sphere has is that it does NOT come with a Capacitor..... something LRP even mentions it RECOMMENDS on their User Guide!!! To make matters worse, the Capacitor they recommended (part of their "Cooling Set" including a Fan - Part # 82500) was not avavilable for purchase even months after their original Sphere was released!?! At another thread it was mentioned that a Capacitor was not needed for all applications and that most likely it was needed for Touring Car racing.... and not Off-Road. Talk about B.S. - My first and original Sphere didn't last 3 laps in my Original BJ4 on it's first ever run! The settings were fine and I was NOT overgeared which is why I couldn't understand what had happened?! After sending it back to Associated they told me the Fetts blew. I asked how that happened... but unfortunately they could not explain what caused it?! To Associated's credit they replaced the entire ESC and Motor. Kudos to them for that. Problem was they (or LRP actually) still could not supply me with the "needed" Capacitor that LRP recommened because LRP still didn't have them available!? I decided to install my new LRP Sphere and 3* Motor on my Associated T4. It ran perfectly and the throttle was very smooth.... I won races with it but the only problem was that after running about 6-7 minutes during practice it would shutdown?! Again, I asked why at various online threads where reps of LRP often posted. They couldn't give me a clear answer and basically couldn't give me a solution either. Again, I was NOT overgeared. Neither the ESC nor the Motor were very hot after 6-7 minutes so it is unlikely that a thermal shutdown was the problem. Finally maybe two months later some LRP "Cooling Sets" were trickling into the States. I managed to score one from Tower (who had them in very short supply at the time) and installed the Cap to my ESC. Low and behold problem solved!!!!!

Now tell me... After spending about $260 for the Sphere and Neo-One combo... how much fun would it be to later learn (on your own after a lot of trial and error) that you got to spend another $20 for a NEEDED "Cooling Set" just to run your brand new ESC and Motor properly and as "Recommended" by the manufacturer?!? Couldn't they at the very least release the "Cooling Set" at the same time the ESC and Motor were released to the public since again they themselves RECOMMEND it?! Here is a better idea... how about including the Capacitor and the Fan with the ESC to help avoid potential problems?! If Novak could end up doing it why couldn't LRP?! In the end I guess LRP did learn something when they decided to release the "Sphere Competition" with it's own Capacitor!

I own 4 Novak GTBs and now One Sphere. Never had a problem with any of the Novak GTBs. Customer Service wise NOVAK is also 2nd to none. Charlie is simply AWESOME! I am sure you can figure out which Brushless System I would strongly recommend!
